dB Technologies Opera 15 — 15-Inch Powered Speaker for Live Sound and Events

The dB Technologies Opera 15 is a 2-way active speaker created for performers, mobile DJs, and event hosts who demand big sound from a single, portable cabinet. Its 15-inch woofer and 1-inch compression driver are powered by a 600W RMS Class D amplifier, yielding up to 130 dB SPL. This model serves those seeking an all-in-one PA box for vocals, instruments, and playback in mid-sized venues.

What Makes This Speaker Unique

Unlike many powered speakers in this price bracket, this model incorporates an asymmetrical horn that narrows at the top and widens at the bottom, matching its throw to room acoustics. Linear Phase FIR filters within the 56-bit DSP help maintain coherent sound from the front to the back. Eight EQ presets let users tailor voicing for speeches, bands, DJ sets, or monitor use.

Technical Details — Power, Drivers, and Inputs

With 600W RMS output and 1200W peak power, the amplifier handles dynamic bursts with headroom to spare. The 15" LF driver uses a 2" voice coil to hit 50 Hz, while a 1" compression driver ensures crisp highs.

• Power Output: 600 W RMS / 1200 W peak — live vocals and bass-heavy sets benefit from sustained headroom
• Frequency Range: 50 Hz – 20 kHz (-10 dB) — delivers full-range clarity for music, voice, and instruments
• Max SPL: 130 dB — enough for mid-size venues and small outdoor gigs
• Drivers: 15" LF + 1" compression driver — bi-amped for clean separation between bass and treble
• No external mixer is needed—two combo inputs take a mic and an instrument directly.

Who Is This Speaker For?

Solo musicians, duos, small bands, DJs, and event organizers benefit from a single powered cabinet serving as main PA, monitor, or satellite. Plugging a vocal mic and guitar straight in streamlines setup for solo performers. Portability is enhanced by the 18.3 kg weight and 130 dB SPL output.
